To all whom it may concern:

Be it known that 1,.N1ononas J Gonnonr, a citizen of the United States,and a resident of New Orleans, in the parish of (lrleans and State ofLouisiana, have in vented a new and Improved Flushin Apparatus, of whichthe following is a full, clear, andexact description.

My invention relates to that class of lushing apparatus in which thereis a siphon, and means for starting the action of the siphon.

It is a design ot my invention to provide for starting the siphon by ajet of water supplied directly by the water supply,

and the invention has also for its design to provide a valve controllingboth the water inlet pipe and the jet pipe for starting the siphon. Thevalve is so arranged as to close the branch leading to the siphon andthe inlet pipe in succession, so that the branch pipe is first closedand then the inlet pipe.

An object of the invention. also is to so form and arrange the casing ofthe men tioned controlling valve that an ample suply of Water will besupplied to the jet pipe eading to the siphon.

The invention will be particularly explained in the specific descriptionhereinafter to be given. 1

Reference is to be had to the accompanying drawings forming a part ofthis specie, fication, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a vertical section of a flushing tank provided with aflushing apparatus embodying my invention; and Fig. 2 is a fragmentaryvertical sect-ion on a larger scale.

Referring to the structural formillustrated, the tank 10 has an inletpipe 11 and a siphon 12, of which the shorter leg is in dicated at 13and terminates adjacent to the bottom of the tank 10. may be providedwith a nipple 14, or equivalent fitting forming a connection between theinlet pipe 11 and the casing 15 of a piston valve 16. From the casing1.5 an outlet 17 leads to the interior of the tank, and an outlet 18communicates with a branch pipe pipe,

19, the outer end of Which is upturned and extends Within the shorterleg 13 of the siphon, as at 19 The float arm 20 connects withthestarting lever 21 by connect The inlet pipe 11 ing elements hereinafterdescribed, and acts also to raise the valve, preferably through a systemof compound levers. Thus the float arm 20 is provided with a dependingT-head 22 fulcrumed at one end, as at 23, on a bracket arm 24-. carriedby the valve casing 15, while theopposite end of the T-head 22 connects,as at 25, with a connecting rod or pull rod 26, the upper end? of whichconnects with the mentioned starting lever 21. A link 27 may connect atits upper end, as

- at 28, with the T-head 22 at about the center,

so that the T-head acts as a lever in connection with the link 27 thelower end of the link connects with a valve-engaging arm or lever 29,which is fulcrumed at its outer end on a bracket arm 30 that issupported on the valve casing 15, and may be integral therewith. Theconnection between the link 27- and the valve lever 29 is at a pointbetween the'ends of said lever, and the free end of the lever 29 extendsinto a recess or slot 31 in the valve 16.

The valve casing 15 adjacent to the outlet 17 leading to the tank, isprovided with an annular chamber 32, communicating with the interior ofthe nipple 14- and with the outlet 17 in order to maintain an amplesupply of water at this point. Similarly, there is formed adjacent tothe outlet 18 leading to the branch 19 an annular chamber 33communicating with the interior of the valve casing and with the saidoutlet 18, in order to insure an ample supply of water leading to thesaid outlet.

The short leg 13 of the siphon may be formed with an internal bead 3 1:to provide a contraction in the said leg adjacent'to the extreme end ofthe upwardly projecting member 19 of the branch. pipe, so that the jetof Water directed through the said branch pipe upwardly into the leg mayhe more eiiective in starting the siphon action by causing an overflowin the leg.

too

"flow in the said leg 1 outlet 18 leading to the branch pipe, so thatwater Will now flow also from the inlet pipe 11 through the nipple 14 tothe branch pipe 19 and be directed in the form of a jet into the leg 13of the siphon, causing an overand starting the siphon action. The tankaving been emptied and the siphon action stopped, the Water from theoutlet 17 will gradually fill the tank. As the tank fills, andthe valve16 is lowered. bythe float, the valve will first cut oil the branch pipe19 so that the siphon action cannot be again started until the startinglever is pulled. As the waiter continues to rise in the tank, the floatwill geventnally move the valve 16 downward to its seat 35,

' closing the inlet pipe 11. i

An important advantage of the described construction is that the fullflow of water is obtained to the tank and to the'siphon leg for startingthe siphon, and by moving the valve only a very short distance. Theconstruction also insures that the branch leading to the siphon leg iscut off while the tank is partially filled, to avoid the possibility ofthe siphon starting again.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent: 7

An inlet valve for flushing tanks comprising acasing having means atone end for connection with aninlet pipe, an outlet for dischargingWater to the tank, and an other outlet for receiving a connection to asiphon, and a valve movable in said casing, the said valve in itsclosing movement first closing the said second outlet and then closingthe first-mentioned outlet.

2. An inlet valve for flushing tanks, com prising a casing having means'for connec tron with an inlet pipe, a side outlet for discharging waterto the tank, another side outlet for receiving a connection to a siphon,the said casing having interior annular grooves leading to said outlets,and a cylindrical valve movable in said casing, the said valve in itsclosing movement first closing the said second outlet and then closingthe first-mentioned outlet, the valve in its opening movement openingsaid outlets in the; reverse succession.

3. An inlet valve for flushing tanks, comprising a cylindrical casingand a cylindri cal valve movable axially in said casing, the casingbeing open at one end and having at said end means for connection withan inlet pipe, the casing furthermore having a valve seat surroundingthe bore thereof, at a point between the ends, on which the valve'niayseat, an outlet to the tank adjacent to said valve seat, and a secondoutlet adapted to be connected with'a siphon, the valve being movable insuccession past the two outlets. and to and from the mentioned valveseat,
